Monday Warmup: Push vs. Drift (2013-05-06)

We saw many simulations where we could push an object or let it drift. Can you spot the difference from a velocity-time graph?

1. What happened during STAGE A of this voyage?

It gained speed.
It had a steady speed.

2. What happened during STAGE A of this voyage?

It got an unbalanced push from behind.
Any pushes or pulls were completely balanced.

3. What happened during STAGE B of this voyage?

It gained speed.
It drifted at a steady speed.

4. What happened during STAGE B of this voyage?

It got an unbalanced push from behind.
Any pushes or pulls were completely balanced.

Monday Exercise: Reading a V-t Graph (2013-05-06)

This Quia exercise gives you a chance to read a basic Velocity-time graph to tell the story of an object in motion.
